The power produced by solar panels is greatly influenced by its position towards sunlight. The more solar panels are perpendicular to the sunlight, the more power is produced. The aim of this research is creating a prototype of the solar panel position control system so that the position between the solar panels against the sun is always perpendicular. The solar panel position control system used in this study is based on image processing. In image processing, the webcam is used to take a shadow image of a bolt measuring 4 cm in diameter and 1 mm placed on a flat plane. Then, the image from the shadow of the bolt is processed to get the angle of view direction of the sun. Furthermore, the angle position is used as input for the solar panel drive motor. Thus, the position of the solar panel can adjust the direction of the incoming sunlight and its position becomes perpendicular to each other. From the results of the research conducted it can be concluded that the prototype can always follow the direction of incoming sunlight with an accuracy rate towards the center point is 95% for X-axis and 96% for Y-axis.
